HARP FIXTURE FOR LAMPS.

Application filed January 27, 1922. Serial No. 532,255.

To all whom z'tjmay concern: I Be it known that I, CORTLAND W, DAVIS,acitizen of the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Harp Fixtures for Lamps, of which the following is aspecification. Y

The invention relates to harps such as are employed for pendentlysupporting lamps and lamp shades,; objects thereof being to produce aharp which is so constructed as to simplify the construction of thecomponent parts, to render the assembling of the parts easy forunskilled labor, and to secure compactness in packing for shipment,whereby the users of lamp-supporting devices may be able to secure harpsof convenient construction at a minimum cost. The lamp harp of myinvention contains pieces of metal made according to pre-determineddesigns of such character that they may be readily set up by the userand united by the use of screws or other simple devices without theexercise of more mechanical skill than is possessed by the ordinaryindividual. The several parts are stamped or otherwise fashioned intofinal shape at the factory, and are ready for the assembling operationby the user without alteration.

The harp includes a top bracket, side bars having at their upper endsholes into which malleable lugs of the bracket extend, ashade-supporting ring secured to the side bars by bolts and carryingclips and screws for retaining a shade fixedly in position, and alamp-supporting ring attached by bolts to the lower ends of said sidebars 'for receiving the bowl of a lamp. These rings are recessed toreceive the side bars, and both the rings and the side bars are madefrom flat stock metal which requires no machining.

The invention will be best understood if reference is made to theaccompanving are of different sizes, but to afford room for the bowl ofa lamp and also, give to the harp a pleasing ornamental design. Q

The bracket2 is made of flat malleable metal, and is provided witha'hole 3 for the reception of a sustaining hook and with lugs 4extending through holes 5 in-the inwardly bent upper ends 6 of; the sidebars 1, the-extremities of these lugs being upset to insure a secureunion of the parts.-

The lamp ring 7 is made adjustable forconvenience in inserting a lampbowl, but the means of adjustment constitutes no part of the presentinvention. This ring is bent at diametricallv opposite sides to forminner recesses or seats for the lower ends of the side bars 1, screwbolts 9 extending through coinciding holes in the ring and the side barsbeing used'to fixedly unite these elements.

The shade ring 10 is bentv to form diametrically disposed externalrecesses 11 for the reception of the side bars 1, and the union of theparts is effected by screw bolts 12 extending throughcoinciding holes inthe ring and the side bars. Clips 13 and screws 14, constituting no partof this invention, are attached to the shade ring for the purpose ofsupporting and looking a shade in position-on the harp.

The shade ring 10, with the external recesses 11 and the clips 13,provides a support for a lamp shade of a diameter large enough to mounta shade large enough to pass down over the outwardly-bent sections ofthe upper end of the side bars 1 to the shade support. The lamp rin 7with the inner recesses 8 allows the attachment of the side bars 1without interference with the support of a circular ilamp bowl from theupper edge of the lamp ring 7.

From the foregoing it will be seen that the several parts of my harpare, with the exception of thebracket 2, made from common flat metalstrips which have merely been bent to the required shapes and perforated at suitable points for the reception of the respective retainingdevices, and that the bracket is of simple character requiring noparticular skill in its production since it may be stamped in a usualmanner. When the harp fixture is packed ready for trans portation totheconsumer, it will be seen that it may be assembled ina package ofrelatively small dimensions as the shade ring 10 and -tl'ieilamp ring 7,111 ese a1-ab1e complete entities that may bel'aid flafi'ivit-h the sidebars. The assembling of the fixture is easily accomplished by thec0nsumer with t the aid cf a s ci ew fdfivei' only. I

Having thus assented myihvenaen', wine I claim is: I
